Injectors for 2003 LB7

I am trying to help a buddy out finding some new injectors for his 03 LB7.

Could I get price quotes on the following:

Re-man stock injectors
New stock injectors
Aftermarket injectors

He uses the truck to tow daily, and has intake, exhaust, and a mild PCM flash. He likes the extra power, but doesn't want to have to monitor vitals. I don't know enough about the D-Max's to give him good advice with injectors.

Thanks alot!
